    摘要: A stent delivery system configured to deliver a stent to a target region of a body lumen may include a catheter; a stent associated with the catheter, the stent having a first region and a second region; a balloon associated with the catheter, the balloon having a first balloon portion associated with the catheter proximate the first region of the stent and a second balloon portion associated with the catheter proximate the second region of the stent; and a sheath about the stent and the balloon, the sheath maintaining the stent in an undeployed configuration for delivery to a target region of a body lumen. The sheath may comprise a first sheath region configured to split at a first pressure thereby permitting the first region of the stent to assume a deployed configuration, a second sheath region configured to split at a second pressure thereby permitting the second region of the stent to assume a deployed configuration, the second pressure being greater than the first pressure and the first pressure being insufficient to cause the second region of the sheath to split, a split-stopping structure between the first and second sheath regions, the split-stopping structure being configured to prevent a split from propagating from the first sheath region to the second sheath region at the first pressure.
